Pneumatic tire

Abstract

In a pneumatic tire in which a carcass layer is turned up from a tire inner side to a tire outer side around a bead core of each bead portion, a transponder is embedded between the carcass layer and a rubber layer disposed in a sidewall portion on an outer side of the carcass layer, the transponder extending along a tire circumferential direction in contact with the rubber layer, and the transponder is disposed 10 mm or more away from an end of a turned up portion of the carcass layer in a tire radial direction.

         8 . A pneumatic tire comprising:
 a tread portion extending in a tire circumferential direction and having an annular shape;   a pair of sidewall portions respectively disposed on both sides of the tread portion; and   a pair of bead portions each disposed on an inner side of the sidewall portions in a tire radial direction,   a bead filler being disposed on an outer circumference of a bead core of each bead portion,   at least one carcass layer being mounted between the pair of bead portions,   a plurality of belt layers being disposed on an outer circumferential side of the carcass layer in the tread portion, and   the carcass layer being turned up from a tire inner side to a tire outer side around the bead core,   a transponder being embedded between the carcass layer and a rubber layer disposed in the sidewall portion on an outer side of the carcass layer, the transponder extending along the tire circumferential direction in contact with the rubber layer, and   the transponder being disposed 10 mm or more away from an end of the turned up portion of the carcass layer in the tire radial direction.   
     
     
         9 . The pneumatic tire according to  claim 8 , wherein
 the end of the turned up portion of the carcass layer located in the sidewall portion on an outermost side in a tire width direction is disposed between a position located on an outer side of and 5 mm away from an upper end of the bead filler in the tire radial direction and a position located on an inner side of and 15 mm away from an end of the belt layer in the tire radial direction, and   the transponder is disposed on an outer side of and 15 mm or more away from an upper end of the bead core in the tire radial direction.   
     
     
         10 . The pneumatic tire according to  claim 8 , wherein a center of the transponder is disposed 10 mm or more away from a splice portion of a tire component in the tire circumferential direction. 
     
     
         11 . The pneumatic tire according to  claim 8 , wherein
 a distance between a cross-sectional center of the transponder and a tire outer surface is 2 mm or more.   
     
     
         12 . The pneumatic tire according to  claim 8 , wherein
 the transponder is covered with a coating layer, and   the coating layer has a relative dielectric constant of 7 or less.   
     
     
         13 . The pneumatic tire according to  claim 8 , wherein
 the transponder is covered with a coating layer, and   the coating layer has a thickness ranging from 0.5 mm to 3.0 mm.   
     
     
         14 . The pneumatic tire according to  claim 8 , wherein
 the transponder comprises an IC (integrated circuit) substrate storing data and an antenna transmitting and receiving data, and   the antenna has a helical shape.   
     
     
         15 . The pneumatic tire according to  claim 9 , wherein a center of the transponder is disposed 10 mm or more away from a splice portion of a tire component in the tire circumferential direction. 
     
     
         16 . The pneumatic tire according to  claim 15 , wherein
 a distance between a cross-sectional center of the transponder and a tire outer surface is 2 mm or more.   
     
     
         17 . The pneumatic tire according to  claim 16 , wherein
 the transponder is covered with a coating layer, and   the coating layer has a relative dielectric constant of 7 or less.   
     
     
         18 . The pneumatic tire according to  claim 17 , wherein
 the transponder is covered with a coating layer, and   the coating layer has a thickness ranging from 0.5 mm to 3.0 mm.   
     
     
         19 . The pneumatic tire according to  claim 18 , wherein
 the transponder comprises an IC substrate storing data and an antenna transmitting and receiving data, and   the antenna has a helical shape.
